Enhanced Television Services

ABSTRACT

A method and system to permit TV viewers to interact with program content broadcast over a subscriber network, such as cable, satellite, internet, or cellular telephone. The details of the ability for the viewer to interact is embedded as data in the program signal. The subscription provider broadcasts a visual indicator as a small icon during programming that informs the viewer that interaction is permitted. The viewer then uses a remote control to purchase products, vote on events, respond to polls, download files, request information, and request callback actions. The TV viewer uses the remote control to send information to a set-top box front-end application, and to iteratively create transactions that are batched and then sent to a back-end core application and database which then handles fulfillment.

BACKGROUND OF THE INVENTION

Historically, television technology developed so as to mirror radio technology. Television was broadcast via electromagnetic waves in analog mode. Television pictures were broadcast using amplitude modulation (AM band), and sound was broadcast using frequency modulation (FM band). As with radio, a television viewer had control over three elements:

1. on-off control,

2. channel control, and

3. volume control.

During the early 1970's, infrared remote controls were introduced to control these same elements on television sets. Until that time, television broadcasting was limited by relatively low bandwidth. The number of channels and controls were limited by bandwidth. Establishment of new television stations were limited by the Federal Communications Commission (FCC). The problem was somewhat alleviated by introduction of ultra-high frequency (UHF) broadcast capability. However, UHF channels never achieved much popularity. Cable television service provided television transmission with increased bandwidth. Suddenly, television viewers were able to access a large multitude of channels. Some television stations broadcasted their programming exclusively for cable, while others simulcast their programs both over the airwaves (electromagnetic) and over cable. Other than the increased number of channels, the main discernible difference between “cable TV” and “broadcast TV” was that viewers had to pay for cable service while broadcast TV remained essentially free. Cable providers provided their users with a “cable box” to enable tuning control. Cable-ready television sets were developed to enable users to plug the cable directly into their sets.

Without a list of what programs were playing on what channels at a given time, viewers would have to “channel surf” until they found programs that they wanted to watch. Cable service providers began to transmit a program “guide” that was accessed from the remote control. Previously, viewers used newspaper listings and magazine type guides to help with their programming selection. Now, a viewer could use the remote control to select and switch to a channel based upon a desired program. So, the number of control elements were increased.

Next, the cable service providers introduced “Pay Per View” programming. Here, not only could a viewer select a special program for viewing at a specific time, but they could also approve (e.g., by pressing the OK button) or not approve (e.g., by pressing the EXIT button) the charges associated with viewing the selected program. With the introduction of digital (as opposed to analog) transmission to cable broadcasting, parents could block channels or specific programs that they did not want their children to watch. On-Demand programming provided viewers with new options that would enable them to watch special programs whenever they wanted. Finally, DVR afforded viewers with the ability to record programs, to time-shift viewing, to pause live TV, and to rewind and move forward through recorded programs and live TV.

All of these new features required the introduction of television remote control units having many more controls than the traditional on-off, volume, and channel controls. Not only are remote controls themselves more sophisticated, but many new television sets may only be controlled using remote controls. These new sets no longer have external controls. Even the brightness, contrast, color, and hue settings are now controlled remotely. Viewers can use their remote controls to control television settings separately form cable settings. They can also use their remote controls to control peripheral devices such as VCR's, DVD's, CD players, etc. With the availability of high-speed internet service over cable television lines, keyboards are often connected to television sets for access to the internet. In some hotels, television viewers can pay their lodging bill by using the remote control. Into the television provider mix also came local telephone companies and satellite broadcasters. These providers advertise even greater increases in bandwidth and possibly more services. So, control over television viewing has become quite sophisticated.

Nevertheless, television viewing essentially remains as a passive activity. Viewers still only turn their sets on or off, control the volume, and select what they want to watch either now or in the future. Cable providers are able to determine what programs are being watched by their viewers. But, viewers cannot actively communicate with cable providers or broadcasters while watching television.

Interactive television is very attractive to cable service providers. Cable companies are in the process of adopting the “Enhanced TV Binary Interchange Format” (EBIF) and the “Open Cable Application Platform” (OCAP). EBIF is a multimedia content format defined by a specification developed under the “OpenCable” project of CableLabs (Cable Television Laboratories, Inc.). The primary purpose of EBIF is to present to a television viewer one or more multimedia pages, similar to web pages, but specialized for use within an enhanced television or an interactive television system. Action sequences are executed as a result of firing certain predefined events, such as a page load event, a key press event, a click event, etc. These events are triggered by the viewer using the remote control. Execution of all events are serialized and controlled by event handlers. On the other hand, OCAP, is an operating system layer designed for consumer electronics that connects to a television system. Unlike operating systems on a personal computer, the cable company controls what OCAP programs run on the consumer's set. Also designed by CableLabs for the cable networks of North America, OCAP programs are intended for interactive services such as eCommerce, online banking, Electronic program guides, and digital video recording. The OCAP standard has not yet been approved by the FCC.

A Multiple System Operator (MSO) is an operator of multiple cable television systems. A cable system in the US, by FCC definition, is a facility serving a single community or a distinct governmental entity, each with its own franchise agreement with the cable company. Though in the strictest sense any cable company that serves multiple communities is thus an MSO, the term today is usually reserved for companies that own a very large number of cable systems.

A number of systems currently exist to purchase items associated with content broadcast over television. An intuitive mechanism for accomplishing such a task would be to have a website associated with a television program. The TV viewer would have a computer alongside the television set. The TV viewer accesses the broadcast content and the website concurrently. Interaction with the broadcast content occurs over the internet on the computer. One such implementation is employed by http://www.shopnbc.com. This corresponds to an NBC network cable channel, shopNBC. This channel is a home shopping channel where viewers can purchase products that they see on television. However, instead of calling a telephone number to make their purchases, viewers purchase the products over the World Wide Web. A web application exists on the website that allows viewers to watch the programming streaming on their computers, thereby eliminating the necessity of having a separate television set alongside the computer. This application exists for the shopNBC channel only, and viewers cannot switch to watching other channels.

US Patent Application Publication No. 2006/0031285 to Ruhnke, et. al. teaches an audio and video On Demand type application along with the business functions required therefore. On Demand programming is not truly interactive. While a TV viewer may use a remote control to access the content, that does not happen interactively with broadcast content. On the other hand, US Patent Application Publication No. 2009/10018898 to Genen, teaches a method of interactively accessing music and other media associated with broadcast content using a remote control. However, there is no back end application associated with this application to provide for fulfillment. The website http://ensequence.com provides synchronized interactivity using a remote control. This application permits a TV viewer to purchase products, vote, receive targeted offers, access sports specifications. It also permits children and teenagers to participate in the activities programmed into the broadcast content. However, this application also lacks a back end to provide for fulfillment.

SUMMARY OF THE INVENTION

The Present Invention provides a way to cater to an untapped market through an innovative suite of products and services bundled as Enhanced Television Service (ETS). ETS functions both on an EBIF and OCAP platform. The Present Invention delivers a host of interactive functions specifically tailored to the broadcast program or commercials. The enhanced and empowered media is then transmitted to the MSO in any one of the many available formats for eventual transmission to the viewer. Invisible and unobtrusive until invoked by the viewer's existing remote control, the enhanced media suddenly reveals a wealth of onscreen information and choices. With no additional equipment installation or modification, the standard cable television remote control transforms the once passive viewer into a participant ordering information downloads, voting, responding and making instant purchases. The ETS handles all of these transactions from order processing to billing and fulfillment. By delivering a host of interactive functions, cable television operators empowered with the ETS solution can increase their competitive position while maximizing their networks financial potential. Through an intuitive portal application, advertisers are able to create and manage their own enhanced television events. They control the look, feel and exact moment the trigger is available to the viewer. Advertisers/Vendors can also upload products for sale or download and associate them with events described above. The portal also provides statistical data on the performance of events in a dashboard like manner. Also through an intuitive web portal subscribers can look at order history, wish lists, download items and purchase promotional products. This web portal resides in the MSO's web portal. Again ETS handles all of these transactions from order processing to billing and fulfillment.

A TV viewer will hereinafter be referred to interchangeably as a subscriber or a viewer. Subscribers can interact with the broadcast program or commercial with the remote control. They can participate in the following transactions using the ETS system:

1—Purchase

By using the remote control, a subscriber can view the products on the panel of the TV and they are able to purchase that product.

2—Polling/Voting

By using the remote control, a subscriber can vote for a particular event that is shown on the TV.

3—Request/Download Information

By using the remote control, a subscriber can request any particular information. They can also request an information download of specific software.

4—View Transaction History

By using the remote control, a subscriber can view their past transaction history on the TV panel. These transactions can be a type of confirmed, unconfirmed and wish list items.

The ETS System provides the following features:

Subscriber is able to interact with the TV using the special remote control to request downloads, purchase products and vote.

-   -   Subscriber is able to view order history, download products and         buy wish list items and promotional items using a web browser.     -   Administrator/Subscriber/Vendor is able to login into the system         using a web browser.     -   Vendor is able to create their own events on the system and add         products associated with those events.     -   Vendor is able to interpret the reporting details mentioned on         the portal.     -   Vendor is also able to maintain and keep track of all the events         they prepared and scheduled to run on the television.     -   Administrator is able to understand the transactions in the         system.     -   Administrator has the ability to manipulate the orders using the         provided portal and tools.     -   Administrators can update and maintain user data, product data         and order data within the system.

Typically, when viewer interaction is possible, an icon (called an iBug) will appear on the screen (usually in the lower right-hand corner). At that point, the viewer will be able to press a button on the remote control that would bring up a menu that is specific to the currently viewed channel. By contrast, the GUIDE button brings up a universal guide no matter what channel is being viewed.

DETAILED DESCRIPTION OF THE INVENTION

The Present Invention allows a TV viewer to use a television remote control to interact with programming content broadcast by a subscription service provider such as cable television service, satellite service provided through a receiving antenna, cellular telephone service, and internet. The TV viewer can purchase a product, vote on an event (e.g., for a contestant on American Idol), request information, or download photographs, audio recordings, ring tones, software, games, and software applications—all using the buttons on the remote control.

The Present Invention allows a TV viewer to interact with the broadcast content using a remote control by associating event identification information with the content. The event identification information, in the form of data, is embedded in the content signals. The event identification data associates the content with an ability for the TV viewer to perform interactive tasks associated with the event by using the remote control. The viewer can purchase a DVD of a documentary while it is being broadcast. The viewer can purchase a product associated with the programming. There is no longer a need to dial a toll free number and to provide a credit card to make the purchase. The credit card information for a particular viewer is already on file with the service provider. When a viewer votes during particular programs, some voting is free of charge, and some voting incurs a charge. For example, voting on American Idol is currently performed by sending a text message on a cellular telephone. The user is charged for the text message. American Idol and the telephone service provider share the revenues from text message charges.

After the event identification data becomes associated with the content, at certain periods during the broadcast, a display indicator becomes visible on the screen. For example, the Discovery Channel might have a small circle with the letter “D” circumscribed therein. The display indicator is a signal that the viewer is able to interact with the programming. When the viewer sees the display indicator (and only when the viewer sees it) can he perform the interactive tasks. The viewer interacts with the broadcast content by pressing buttons on the remote control. The keystrokes are then transmitted to the set-top box. In a two-way conversation between the set-top box and the service provider, the keystroke information is sent to the service provider which starts a transaction, the service provider transmits a response back to the set-top box, and the response is displayed to the viewer in an intelligent fashion. A series of two-way communications between the viewer and the service provider collects data to iteratively form a transaction by concatenating all the data together.

FIG. 1 is a conceptual model which gives a high-level overview of the system. In a typical production scenario, there will be multiple MSO's and one ETS Core system. These MSO's will be geographically located and every MSO will have one ETS Edge. A TV viewer interacts with the set top box application using a remote control. The user data flows from the Set Top Box Application to the ETS Edge, and then the data flows to the ETS Core system. When an event is created in the ETS Core system, the event data flows to the ETS Edge and then to the Set Top Box Application.

Every MSO will have multiple ETS Edge systems that are geographically located on its head ends. In addition to multiple ETS Edges, every MSO will have one ETS Core system that is centrally located within that MSO. The data from multiple ETS Core systems will go to the Data Warehouse on regular basis for persistent storage and reporting purposes.

The ETS Core controls:

1. event management;

2. subscriber management;

3. order management;

4. product management;

5. memory management;

6. inventory management;

7. maintenance;

8. security and identity;

9. monitoring; and

10. reporting.

The ETS Core communicates directly with the Data Warehouse which stores information regarding:

1. event management;

2. product management;

3. maintenance;

4. security and identity;

5. monitoring; and

6. reporting.

Third party vendors and shippers (e.g., Amazon) and payment processors (e.g., PayPal) communicate directly with the ETS Core through an MSO network, as do administrators (Admin) and customer service representatives (CSR). Each MSO network has a plurality of ETS Edge interfaces which provided geographically local viewer polling, purchasing, downloading, and event presentation.

FIG. 2 is a logical model of the ETS system. It provides details about:

1. different tiers of the ETS system;

2. protocols used for communication;

3. data flow between the systems;

4. different types of users of the system; and

5. third party systems integration.

Whenever the subscriber interacts with the TV, he or she interacts using the Set-top Box (STB) that is associated with that TV. The customized application (Xlet) that is sitting on the STB will listen to these user interactions. The Xlet application will send the relevant requested data to the ETS Edge system and the ETS Edge will respond back to the Xlet. This transaction data will eventually go from ETS Edge to ETS Core system in real time or near real time basis. The ETS Core system will process the actual transaction. In the same way, when an event is created in the ETS Core system, that event data will be distributed to the relevant ETS Edges. When an ETS Edge receives a request from the TV subscriber, the relevant event data will be sent back to the Xlet in the form of the response.

ETS Edge

FIG. 3 provides a conceptual model that gives a high level overview of the ETS Edge system. The scope of ETS Edge system consists of the following sub-systems:

1. Set-top Application bundle (Xlet application)

2. ETS Proxy system

3. ETS Edge system

FIG. 4 shows a logical model of the ETS Edge. The TV subscriber interacts with the set-top box using the remote control. The set-top application bundle (Xlet) that is sitting on the set-top box listens to those user interactions and sends the user requested data to the ETS Proxy and ETS Proxy sends the same request to the ETS Edge. ETS Edge responds back to the ETS Proxy in the form of XML. The proxy converts the XML into EBIF format data by using TV works 2-way package library. The converted EBIF data is sent back to the Xlet as a response and Xlet sends this dynamic data to the TV so the user can view the dynamic data on the TV as a response to their request.

Though the TV subscriber gets the response from the ETS Edge, the actual order processing will be done by the ETS Core system. The transaction data goes from ETS Edge to the ETS Core in real time (Ex: live polling) or near real time (download, request info) basis as per the configuration settings. The back and forth data transmission between ETS Edge and ETS Core is being taken care of by Oracle TimesTen caching mechanism. The TimesTen gives high performance and scalability at an exceptional level.

User Definitions and Characteristics

Parent:

-   -   Main Account holder.     -   Has a PHONE number and TV PIN associated in the database.     -   Has the billing, email and physical address associations in the         database.     -   Has a Username and Password for the Subscriber Portal.     -   Allows/denies access to the child account via the Subscriber         Portal and sets transaction limits to each of the child         accounts.

Child:

-   -   Authorized user account by the Parent account.     -   Has permission set by the Parent account (enabled/disabled;         transaction limits; etc.)     -   Any wish list items added by the child account go to Parent         account.

Unregistered user:

-   -   An unregistered user is one who never registered with the portal         and tries to purchase using remote control.     -   The following requirements apply for an unregistered user:     -   Allow them to add a product into a PENDING BUCKET with a VALID         PHONE number. Phone number will not be validated as valid or         invalid. If the phone number is already in use, they will be         asked to enter a different phone number.     -   Ask them to register on the portal with the same phone that they         entered during their purchase attempt     -   Once they register with the portal, the system will move the         order from the PENDING BUCKET to their WISH LIST, present the         WISH LIST for confirmation, and process the WISH LIST upon         confirmation

Registered User:

-   -   A registered user is one who already registered with the portal         and makes a purchase using their remote control.

The following requirements apply for a registered user:

Allow them to purchase a product with a VALID PHONE NUMBER and PIN to complete the purchase

If he enters a VALID PHONE NUMBER/WRONG PIN:

-   -   If the number of attempts are within the limit, they will again         be requested to enter their PHONE NUMBER and PIN.     -   If the number of attempts exceed the limit, the system will         respond to the user with a message as ‘Wrong PIN entered. Please         call customer support’.

If they enter a INVALID PHONE NUMBER/PIN, blackout the MAC and ask them to call customer support.

If the user is a child and they try to purchase something beyond allowed transaction limit, then the product will be added to their parent's WISH LIST

MAC ID will not be verified as part of authentication, however it will be checked as whether it is in blackout list or not.

If the user himself wishes to add something into the wish list, allow him to do the same.

2—Download

The system needs to provide a feature where the subscriber should be able to download information that is interesting to them.

3—Polling

The system should provide a feature where the subscriber should be able to vote for a specific event.

4—Event Loading

The ETS Edge should load the event data to the STB based on the request received from the STB.

When the user interacts with the STB using the remote control, the STB Application will identify the current event that is associated with the current TV show the user is watching. Then, the STB Application will send a request to the Edge server to get the current event data. Edge Server will send the event data back to the STB Application so that the User can view the current event information on the TV panel.

ETS Core

FIG. 5 shows the components of the ETS Core. The ETS Core system will contain the following components:

-   -   Web Portals     -   Business Application Engine     -   Common Business Services     -   Third Party Integration Services

Web Portals

The ETS Core system will have the following web portals:

Administrator Portal

-   -   Administrator portal gives the complete ability for the         administrator of the system. To add/remove new users manually,         add/remove products manually, check out the detailed         transactions. Manipulate the transactions etc. CSR staff will         have the role to act as administrators for the complete systems.         Administrator can also assign privileges to different users of         the system.

Subscriber Portal

-   -   Subscriber portal is the place where the user is able to manage         their orders and wish list. It also displays products to the         user based on user interests in hot deals page. The User can         check their activity history on timely basis. User can also         download the products based on the requests they made on the TV.

Vendor Portal

-   -   Vendor Portal allows vendors/advertisers to define events that         are going to be displayed on TV when the commercial or program         is broadcasted. Vendor portal also has reporting ability. The         reporting includes, but not limited to events, products and         geographical region. Vendor Portal allows vendors to add         products (electronic or physical) and update existing vendor         created products.

CSR Portal

-   -   The CSR portal will be used by the CSR to support the customers.

Business Application Engine

Business Application Engine comprises the logic to process the User requests and automate transaction processing. It inserts the order into the core system and applies business logic into it. It contacts the payment gateway to charge the user for the amount of the product (if it is a product sale). All successful transactions will be forwarded to an internal or third party fulfillment center. The confirmation of the transaction will be sent from the third party billing and fulfillment systems. Product sale, download request and voting are all handled as a part of this subsystem.

Common Business Services

Common Business Services can be accessible from any portal and includes the following services:

Order Management

Product Management

Event Management

Inventory Management

Dashboard Management

Identity Management

Subscriber Management

User Maintenance

Third Party Integration Services

These services are used to integrate with third party vendors and include the following:

Datacenter Service

-   -   Datacenter service will be used to send the aggregated polling         data in real time to the broadcasting data center so that it can         be sent to the event location such as a stadium to show the         result on the stadium screen.

Shipment Service

-   -   Third party fulfillment service can be used for outsourcing         fulfillment processing. System uses third party fulfillment web         services to forward order details directly into their systems         and the order will be fulfilled by third party and on subsequent         requests will return the status of the order from third party         fulfillment.

Payment Service

-   -   Payment processing and user detail verification uses PayPal         service. PayPal service takes the user details and charges the         method user requested after validating details given by the         user. (Need to rewrite these and do it similar to the third         party fulfillment)

FIG. 6 shows a physical model of the ETS system. The physical model describes how the ETS Edge and ETS Core system are physically deployed into production. Load balancers distribute the traffic among web servers that are configured in the cluster. All servers are clustered so that when one specific server goes down, the counter part in the cluster will provide the service. So eventually the system will provide high availability and scalability.

FIGS. 7 through 28 are HIPO charts and high-level program flow charts for the ETS Edge system. HIPO was a diagrammatic documentation system for software developed by IBM. Information regarding this system can be found in IBM Publication GC20-1851-1 entitled: “HIPO—A Design Aid and Documentation Technique.” It was originally designed to promote “structured programming.” But, since the introduction of “object oriented programming,” HIPO has fallen into disuse. Nonetheless, it is still an excellent tool for describing software systems. HIPO is an acronym that stands for Hierarchy plus Input, Process, Output. HIPO documentation comprises a series of diagram charts.

The first chart in each series is a hierarchy chart. This chart, appearing like a corporate organization chart, displays the calling relationship between the various system modules. Each module appears as a block in the diagram. Lines connect these modules to show their hierarchy. Hierarchy is further shown by assigning numeric labels to the modules. Normally, the highest order module would be labeled 1.0. Modules immediately below it hierarchically would be labeled 2.0, 3.0, 4.0, . . . , and so on. Modules hierarchically below 2.0 (for example) would be labeled 2.1, 2.2, 2.3, . . . , and so on. Modules hierarchically below 2.1 (for example) would be labeled 2.1.1, 2.1.2, 2.1.3, . . . and so on. So, by looking at the numeric label of any module, one can determine its level of hierarchy. A black triangle located at the corner of the module block indicates that the module is re-used many times either as a subroutine or as an object.

Following the hierarchy chart, each module depicted on that chart receives an IPO chart. The IPO chart is divided into three columns. The leftmost column represents INPUT. The rightmost column represents OUTPUT. The central column represents PROCESS. This is where the various steps in the process are described. Most of the information in the INPUT and OUTPUT columns is graphical (e.g., representing terminals, hard drives, printers, etc.). Most of the information in the PROCESS columns is descriptive text showing the procedural steps. Arrows connect the PROCESS column to the INPUT and OUTPUT columns to show data flow.

Each IPO chart may have an Extended Description showing notes about the various steps in the process. These act almost like footnotes in a document. They are usually too detailed or extraneous to include in the steps denoted in the PROCESS column.

FIG. 7 is a hierarchy chart showing the module hierarchy of the ETS Edge system. Note that there are seven modules:

1. ETS Edge—the main module

2. Purchase

3. Download

4. Poll/Vote

5. Request Info

6. Authentication

7. View Transaction History

Following the hierarchy chart are IPO charts for each of the seven modules, and following each IPO chart is an Extended Description for each module and a standard high-level program flow chart for each module. The charts are self-explanatory. They are grouped as follows:

FIGURES MODULE DESCRIPTION 8 through 10 1.0 Entry Point - Process All Requests 11 through 13 2.0 Process Purchase Order 14 through 16 3.0 Process Download 17 through 19 4.0 Process Polling/Voting 20 through 22 5.0 Process Request Info 23 through 25 6.0 Process Authentication 26 through 28 7.0 Process Transaction History
